I purchased a new Nokia Lumia 720 (IMEI No. 357297059891789) during April month of this year. It was during June 14th my touch screen was not working, which i got replaced with NCC, but on the next day my phone was unable to receive any signal and it was always displaying no service. Again i gave it to NCC two days later, it was on 5th of August I got a reply my phone was tampered, which will not come under warranty, i was shocked. A brand new mobile , just a few days old, more over i took so much care in using the mobile, such an irresistible reply from NCC, i could not digest. Something should be done to this NCC. I really wanted to go to consumer court and fight this injustice. These peoples (NCC and Nokia Co.) are cheating everybody. More over when they called me for the second time to talk about the tampering of my phone, I was asked to sit in a separate room, which usually do not occur. Please I need help in this regard my friends. My sincere advice please do not go for NOKIA..it pains a lot
